don't know anything about the Cape Fear blanks, tho they sound intriquing.
I do know that the loomis hotshot series are a mighty fine blank. I used to build the magnum taper HS 1021 (they still make it). This was one very powerful rod. I've caught 40lbs salmon in swift water with this rod and still had power to spare...
recently i've aquired the loomis HS9000 - slightly lighter blank - in the two piece model. I hope to someday build this into a fly rod...
